Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.
As a flexible power resource, energy storage stations can store and release electrical energy according to the need, thereby balancing load and supply in the power system and enhancing its reliability and cost-effectiveness .
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
The power is positive during energy storage charging and negative during discharging. This means the rated power of the energy storage should be capable of meeting the maximum power requirement in the T period, independent of the charging state, to achieve an active power balance.
Additionally, it can provide the grid with frequency adjustment, voltage support, and other services, enhancing its stability and reliability [8, 9]. When the frequency fluctuates, energy storage stations can swiftly respond to the frequency changes in the power system, offering agile regulation capabilities and maintaining system stability .
A stationary Battery Energy Storage (BES) facility consists of the battery itself, a Power Conversion System (PCS) to convert alternating current (AC) to direct current (DC), as necessary, and the “balance of plant” (BOP, not pictured) necessary to support and operate the system. The lithium-ion BES depicted in Error!
